Description
Technical field
The utility model relates to the utility appliance field of converter structure, is specially a kind of flanged coupling formula furnace axis bearing slag-blocking apparatus.
Background technology
In convertor steelmaking process; have slag, the splash of grain steel around body of heater, although there is the protection of protective shield or kennel closed frame, As time goes on; these slags and grain steel also can enter on trunnion of converter bearing support by the gap between gudgeon and protective shield, affect the normal running of converter.Therefore, be necessary to arrange bearing support slag-blocking apparatus.But the bearing support slag-blocking apparatus structural shape using is at present comparatively complicated, setting accuracy is limited, has influence on the normal operation of converter.
Utility model content
In order to overcome the defect of prior art, a kind of simple in structure, converter utility appliance that setting accuracy is high, easy to use is provided, the utility model discloses a kind of flanged coupling formula furnace axis bearing slag-blocking apparatus.
The utility model reaches goal of the invention by following technical solution:
A kind of flanged coupling formula furnace axis bearing slag-blocking apparatus, comprises bearing support, and the gudgeon of converter is set in the inner ring of bearing support, it is characterized in that: also comprise inner shield ring, outer back-up ring, anti-heat shield and backing ring,
Inner shield ring is flange-like, and the neck flange of inner shield ring is set on gudgeon, and bind round on the outer wall of inner shield ring neck flange the inner of outer back-up ring, and fixing between outer back-up ring and the outer wall of inner shield ring neck flange, the outer end of outer back-up ring is set on gudgeon;
Solar heat protection baffle-plate-sleeve is located on the outer wall of inner shield ring neck flange, and anti-heat shield is located between the flange chassis and the inner face of outer back-up ring of inner shield ring;
Backing ring is set on gudgeon, and outer face and the backing ring of outer back-up ring are fixed.
Described flanged coupling formula furnace axis bearing slag-blocking apparatus, is characterized in that: between outer back-up ring and the outer wall of inner shield ring neck flange, be screwed.
When the utility model uses, the surrounding of anti-heat shield is connected with the framework of converter both sides enclosed hood, for to splash, the slag outside converter body, grain steel etc. once stop, enclosed hood is the fixing steel structure frame being connected into steel welding, in the middle of enclosed hood is trapped among converter, prevent that in steelmaking process, flue dust etc. overflows, two side hole of enclosed hood are with installation shaft bearing; By inner shield ring, outer back-up ring and solar heat protection baffle plate composition sealed structure, slag, grain steel etc. are had to secondary barrier effect, can avoid slag, grain steel etc. to fall on trunnion of converter, avoid slag, grain steel etc. to enter bearing support by the gap between anti-heat shield and gudgeon, thereby improve sealing pushing off the slag effect, avoided the infringement that normal operation brings to equipment.
The utility model can reach stronger adaptability, higher installation convenience, shorter work period and better comprehensive cost performance.The beneficial effects of the utility model are: simple in structure, setting accuracy is high, easy to use, and pushing off the slag and effect of heat insulation are good, have ensured the normal operation of producing.
